What Perception AB does
The plugin sits at two points of a chain: a first instance is inserted before the processing chain and set to Pre, and a second instance goes at the end of the chain and is set to Post. The Match Level toggle then switches between the two states, so the unprocessed and processed signal can be heard at the same loudness. The developer frames this around how louder material tends to sound better at first, which makes reliable judgements difficult without matched levels.
The developer describes Perception AB as able to bypass any processing chain, including external analog gear, and it adds a Bypass All function alongside several loudness matching modes and easy bulk insertion. The VST crack, AU crack and AAX crack names are also searched for the same release.
Key features
- Pre and Post insertion. One instance is placed before the processing chain and set to Pre, and a second instance is placed at the end of the chain and set to Post, which defines the two points that are compared.
- Match Level toggle. Automatic loudness matching lets the user switch between the processed and unprocessed signal while the two stay at matched loudness, which removes level as a factor in the comparison.
- Multiple loudness matching modes. The developer lists several loudness matching modes, so the level compensation can be adapted to the material being checked.
- Bypass any processing chain. The chain under test can be bypassed as a whole, including external analog gear that sits outside the plugin host.
- Bypass All and bulk insertion. A Bypass All function switches every inserted instance at once, and bulk insertion adds the plugin across many tracks in one operation.
- Fast A/B switching. The comparison works as a quick toggle, so before and after states can be auditioned in rapid alternation during a session.
Compatibility
The plugin comes as VST2, AU and AAX for Windows and macOS (64-bit), with minimum support of macOS 10.7 and Windows XP, and native support for Apple Silicon is listed.
